Develop a recipe to make 50 mL of a buffer from assorted chemicals available. Create a buffer by using TWO of the following reagents: NaHCO3 , 0.10 M HCl, NaH2O4, 0.10 M NH3, NH4Cl, NaHPO4, NaC2H3O2, Na2CO3. Create a buffer with a pH greater than 7.0 Carefully select TWO reagents to use for the buffer, determine how much of each reagent to use in order to achieve a concentration between 0.01 M and 0.50 M. You will need to indicate what the desired concentrations of the 2 reagents are. The calculations of its pH will need to be done to verify it falls in the proper range. **DO NOT randomly choose 2 reagents to add together. Remember that a buffer must contain a weak acid and its conjugate base. Use the Henderson-Hasselbalch equation to calculate the theoretical pH of your buffer, based on the desired concentrations you plan to achieve. Show work!!
